Application April 2, 1948, Serial No. 18,675 m 2 Claims.

This invention relates to a pop-up type drain valve and moreparticularly to the actuator connecting portion thereof.

Heretofore in the art of pop-up drain valves the actuator comprises atiltable solid unit having a drain exposed portion and a portiondisposed exteriorly of the drain and operatively associated withsuitable actuating mechanism usually having a manually actuable memberto effect unit tilting to effect in turn valve elevation for draining,the valve seating by gravity for drain closing.

The chief object of the present invention is to provide a valve end ofsuch character that the structure can function as above described andwhich end is suitable for use with substantially ninety-eight percent ofall actuators now in use.

The chief feature of the present invention resides in the actuatorassociated end of the popup valve and its dual possible association withthe actuator.

The full nature of the invention will be understood from theaccompanying drawings and the following description and claims:

In the drawings Fig. l is a sectional View through a conventional pop-upvalve and drain combination, the pop-up valve with the includedinvention being shown in elevation.

Fig. 2 is an elevational view of said valve taken at right angles to thevalve as shown in Fig, 1.

Fig. 3 is a bottom view of the valve.

Fig. 4 is an enlarged sectional view taken on line 4-4 of Fig. 2 and inthe direction of the arrows.

In Fig. 1 of the drawings l indicates a sanitary fixture with drainoutlet l l discharging a. drain l2 connected to a T l5. The dischargetherefrom is indicated at I 3. In the middle branch of the T there issuitably mounted in sealed but tiltable relation, as at 14, the actuatormember having the drain enclosed end l6 and the exposed actuable end H.

The pop-up valve includes valve member l8, stem l9, guide vanes 20 andlower stem extension 2|. The foregoing is old in the art.

Reference will now be had to Figs. 1 to 3 inclusive wherein saidextension 2| includes a diverging portion 22. Depending therefrom, inoifset relation to the stem axis, see Figs. 1, 2, and 3, is the offsethook 23 substantially U-shaped ii P 1) in outline, see Fig. 2. As shownin said figures and Fig. 4 the same in section includes inclined sides24, a semicircular end and a flat opposite end 26, Note that portion 22terminates in shoulder 21, see Figs. 1 to 3.

With the actuator and parts assembled, and with the valve not applied,it will be obvious that if the valve be dropped into the waste line I 2the shoulder 21 will be disposed above the actuator end l6 for valveelevation.

When the actuator and rod are to be connected the valve is turned andthe rod now seats in the U-shaped hook or pocket, see Fig. 2 and asshown in Fig. 1.

In other words if the valve be dropped into the drain, it still will beactuable by the actuator because shoulder 2'! overlies part it. If it isturned sufiiciently the rod seats in portion 23. Certaint ofvalve-actuator operative association for valve elevation is assured atall times.

The invention claimed is:

1. In a pop-up valve structure adapted for tilt rod actuation and havinga valve portion and vane type guide means longitudinally alignedtherewith, the combination of a stem portion coincident with thelongitudinal axis of the valve portion and the means and disposedadjacent the latter, a sidewardly disposed U-hook shaped end upon saidstem portion and disposed in offset relation to that axis and a shoulderextending laterally to said axis and in transverse relation to said endwith respect to said axis, said shoulder and hook end departing from acommon junction thereof with said stem portion.

2. A valve structure as defined by claim 1 wherein the hook-shaped endin transverse section includes a flat face, a pair of converging facesand a convexly curved face.
